When an Item that a user has connected encounters an ITEM_LOGIN_REQUIRED error within a few minutes of it being added, it's likely that one of the following happened:
/accounts/balance/get, or /signal/evaluate when called with a ruleset that includes a balance rule, performs a real-time balance check with the financial institution. Requesting more data immediately after the initial connection can sometimes cause an ITEM_LOGIN_REQUIRED error. Since the data was just pulled when the Item was created, it will be accurate and there's no need for an additional real-time balance check. If you need balance data right after an Item add, the best practice is to use the /accounts/get endpoint, which returns the cached balances object without re-contacting the institution.ITEM_LOGIN_REQUIRED error.Adding products and calling Balance right after an Item add won't always result in an error, but it does happen at times so following the advice here is best practice to reduce friction for your users.
